I will try to create a new version in the next days.
But as only a really small percentage cares about the shader licenses of my free downloadable shaders (not only the fluid shader), my other projects have priority.
(Note: With license I do not mean any order to pay money, I mean the license text)

One question:
You said "replaced the old license with the new". But the new license file is named _v3 and not v_4. And they are in different addon folders.
Just to check if it probably exported a wrong filename._________________Holger SchÃ¶nberger
